测试期间出现不满足的DependencyException

@Component
public class ExportsFacade {

    private SamplesService sampleService;
    private SamplesRepository sampleRepository;

    @Autowired
    public ExportsFacade(SamplesService sampleService, SamplesRepository sampleRepository) {
        this.sampleService = sampleService;
        this.sampleRepository=sampleRepository;
    }

    ...

}

@RunWith(SpringRunner.class)
@DataJpaTest
@AutoConfigureTestDatabase(replace=Replace.NONE)
public class ExportsFacadeTest {

    @Autowired
    private ExportsFacade exportsFacade;

    @Test
    public void export() throws IOException {
        exportsFacade.generateExport();
    }
}

我得到这个错误

org.springframework.beans.factory.unsatifieddependencyException异常: 创建名为“com.lcm.facade.ExportsFacadeTest”的bean时出错: 通过字段“exportsFacade”表示的未满足的依赖关系;嵌套的 例外情况是 org.springframework.beans.factory.NoSuchBeanDefinitionException:否 “com.lcm.facade.ExportsFacade”类型的限定bean可用: 至少需要1个符合autowire候选条件的bean。 依赖项批注: {@org.springframework.beans.factory.annotation.Autowired(required=true)}
